* | Add config_p2p_leases_subnet_prefix_length configurationmarkchien2022-03-311-0/+9
|/ | | | | | | | | | | | | | | | Add new rro configuration which can be used to make the p2p dhcp prefix length larger to reserve the address range outside of leases subnet prefix length for EAPOL-Key feature. This configuration only valid if its value larger than dhcp server address prefix length and config_tether_enable_legacy_wifi_p2p_dedicated_ip is true. E.g.:leaseSubnetPrefixLength = 25, p2p static address = 192.168.49.1/24 dhcp range: 192.168.49.0 ~ 192.168.49.127 (192.168.49.1/25), reserved 192.168.49.128 ~ 192.168.49.255 for EAPOL-Key feature.

* Set the limit whenever any IPv4 or IPv6 rule exists.Lorenzo Colitti2021-04-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Currently, BpfCoordinator only sets the data limit on a given upstream whenever the first IPv6 rule is created on that upstream, and clears it whenever the last rule is deleted on that upstream. It never does this when adding or removing IPv4 rules. This makes it impossible to offload traffic on IPv4-only networks. Fix this by setting the limit when IPv4 rules are created or deleted as well. Test: atest TetheringCoverageTests Manual tests as the follows Test {add, clear} limit with IPv6-only network [OK] Test {add} limit with IPv4-only upstream [OK] TODO: Test {clear} limit with IPv4-only network. blocked by aosp/1579873 because the IPv4 rules have never deleted.

* [BOT.6] Make BpfCoordinator to support data limitHungming Chen2020-06-091-46/+124
| | | | | | | | | | | | | | | | | | | | The BPF tethering coordinator listens to the forwarding rule changes for updating data limit which is applied in the following conditions. - After adding the first rule on a given upstream, add data limit. - After removing the last rule on a given upstream, clear data limit. - The service applies a new data limit on current upstream. The reason for relying on rule changes is because the Tethering and IpServer objects have multi-internal state machines. It is hard to synchronize all of their states. Note that the data limit cleanup for stopping or switching upstream relies on offload rules are all removed as well. Bug: 150736748 Test: manual Change-Id: I829d36339973f9473fe6b616c48aa288f18d1c46

* Tethering: ensure downstream prefix do not conflict with upstreammarkchien2020-05-271-24/+43
| | | | | | | | | | | | | | | | | - Add New class PrivateAddressCoordinator to coordinate the private address conflict problem. - Downstream prefix would be random in 192.168.0.0/24 ~ 192.168.255.0/24. - If new upstream prefix is conflict with existing downstream prefix, downstream would be kicked out and it would request a new one. - The last conflict upstream prefixes would be blacklist. Avoid to select downstream prefix which is conflict with prefixes in blacklist. Bug: 130879722 Test: -build, flash, boot -atest TetheringTests Change-Id: Ib45b87bcd9eeb5da03fb7ec90b1af9ca53998cf5
* Adjust TTL for ipv6 tetheringmarkchien2020-05-241-8/+54
| | | | | | | | | | | | If upstream is cellular, set the TTL in Router Advertisements to "network-set TTL - 1" for carrier requirement. For other non-cellular upstream, set TTL as "network-set TTL + 1" to preventing arbitrary distinction between tethered and untethered traffic.

* Don't crash when receiving an RTM_DELNEIGH or NUD_FAILED.Lorenzo Colitti2020-04-141-3/+5
| | | | | | | | | | | | | | | | These events don't have MAC addresses, so the code attempts to create an Ipv6ForwardingRule with a null MAC address. This crashes when attempting to get the raw MAC address bytes to send to netd in the TetherOffloadRuleParcel. This was not caught by unit tests because the test exercise this code path in a way that is not correct (by sending RTM_DELNEIGH and NUD_FAILED events with MAC addresses). Fix the unit tests to properly pass in null MAC addresses for these events. Bug: 153697068 Test: fixed existing tests to be more realistic Change-Id: I26d89a81f1c448d9b4809652b079a5f5eace3924

* TetheringManager API clean upmarkchien2020-03-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Per API review: - @IntDef defined on the type integer parameter - have getters on each parameter that is set in the TetheringRequest.Builder - new added API should not be deprecated Below APIs is moved from system-current to module-lib-current that only plafrom code(e.g. ConnectivityManager and Settings) can use them. TetheringRequest. onTetherableInterfaceRegexpsChanged, TetheringInterfaceRegexps: Only platform code can use them because interfaces by regular expressions are a mechanism which is planning to be deprecated. Also rename some constants for easier to understand.
